4 (o1. fis-im 6 Claims.

This invention relates to a shing tip-up and more particularly to aspring-loaded sh line holder that is releasable by a pull exerted on theline,` as by a biting sh, and will automatically jerk the line to causethe hook to be embedded in said biting fish.

It is an object of this invention to provide a spring-loaded sh lineholder that is releasable by a pull exerted on the line, as by a bitingsh, and will automatically jerk the line to cause the hook to beembedded in said biting fish.

It is another object to provide a tip-up that is reset by a singlemotion of the hand.

It is still another object of this invention to provide a tip-up that isresponsive to Vpulls of selected magnitudes.

It is a further object to provide a tip-up, the parts of which interftastride each other to form a compact assembly.

It is still a further object of this invention to provide `a triggeractuated tip-up,` the trigger sensitivity of which remains substantiallyconstant throughout the trigger movement.

It is a final object to providea tip-up that has a supporting armadjustable in elevation and azimuth.

Other objects and many of the attendant advantages of this inventionwill be readily appreciated as Athe same becomes better understood byreference to the following detailed description `when considered inconnection with the accompanying drawings in whichlike reference nupartsthroughout the figures embodiment of the invention in its cockedposition with parts in section.

Fig. 2 is av plan view of the invention. in its fully released positionwith parts in section.

' Fig. 3 is a plan view ofthe invention.

Fig. 5 is a sectional'view of a modified form showing the triggershoulder in latched engagement with the catch. Referring now to thedrawings wherein like refprovided with an arcuate erenee charactersdesignate like or corresponding parts throughout the several views,there is shown in Fig. 1 (which illustrates a preferred embodiment)supporting arm II made ofsheetl steel formed into a U-shapedcross-section, said arm being normally positioned so that the open sideof the U is directed downwardly, and the Vclosed side upwardly. One endI2 of said arm isv adapted to bevmounted on a support I3 mounted on a U-shaped clamp I4.

The U-shaped clamp is provided with the usual thumb screw I5 fortightening to any member such as a boat gunwale.

The support member I3 is a cup-shaped element mounted inverted on thetop or closed side of the U-shaped clamp I4. The top I6 of thecup-shaped member is recessed concavely spherically to receive insliding engagement thereon the spaced and correspondingly arcuatedportions II on the end I 2 of arm II. This arrangement, construction andassociationof the companion arcuate portions I1 and the concavespherical cup top I5 allows arm I I to be moved in azimuth and in'elevation as desired. Any desired adjusted position of the arm II can beheld secure by the tightening of wing nut I8 on the bolt I 9. The closedend of U-shaped clamp I4 and the concave spherical top I are centrallyapertured at 20 and 2|, respectively, and the closed side of the U-shaped arm is also apertured at 22 in registry with ately into thespaced leg sides of the U-shaped arm II to receive a correspondingarcuately cut washer 23. lThe arcuated portion of the washer 23, thearcuated portion 22, and the arcuated portions II areconcentric toprovide true elevational movement of arm I I.

The top and one leg of U-shaped clamp I4 is slotted at 24, fromaperturel to terminus 25 to allowthe arm II, the support member I 31,and the bolt `I!! toV be slid `into a similaroperative position on leg26 of U-clamp I4 to accommodate clamping to the side of a boat gunwaleas differentiated from clamping overthe top of the gunwale. n Pivotablearm 21. made of sheet steel formed into a U-shaped cross-section, ispivoted to supporting arm II -as at 2 The U cross-section of pivotablearm `21 is larger than the U crosssection of supporting arm latch 30pivoted thereto at 3 I. Pivot 3I is spaced downwardly of pivot 28 toprovide an arrange` companion extending lug 34. A tension spring 32 isconnected to said projection 33 and is anchored to lug 34, thus springloading arm 21 for pivotal movement upwardly relative to the supportingarm II.

Trigger 3D, pivoted at 3|, is an elongated arm extending beyond the endof pivotal arm 21, and has apertures 35 and 36 at its end to receive andsecure therein the end of a iish line. The pivot end of saidtriggerzissprovided with anint'egral projection 31 which is aperturedat' 38'to` receive a hook end of tension spring said spring 39 beingengaged with the eye of eyebolt 4U anchored to the apertured endwall-471;'

The angular,-A displacementfoi pivotal'arm'fZ'l is limited by catch 43,and arm edge 5I.:

For trolling, the arm is secured by the wing nut I8 in an elevatedposition for the best response for that type of shing.

The latched or cocked position of the device is shown in Fig. l. It willbe noted that pivotal arm 21 is biased to pivot upwardly, but isconstrained by the latched engagement of trigger 3G, carriedfbysaidpivot arm',- withzthe catch 43 on supporting arm II. As aciishnibblesonthe hook l 46 and tends to pull or swim with it that motion iscommunicated to the trigger 30 through means ofi. line 41 resulting inthe trigger end being pivoted downwardly about its pivot 3l. After a ofsaid pivotal movement the. 1trigger.,becomes unlatched from catch 43thereby releasing spring loaded arm 21 which is violentlyvpivoted andthrust upwardly, jerking the line and hook along with it as shown inFig. 2. rihisffactionl embeds. the hook' in thebiting shs mouth 4andsecures-the saine for'thc fisherman. to bepulledinratwill.
